It is ideally suited for single ply roofing membrane and peroxide cured heat resistant coolant base.
Main Characteristics:
Semi-crystalline
Low diene
High molecular weight
Heat and UV stable
Medium Molecular Weight Distribution
Applications:
Single ply roofing membranes
Peroxide cured, heat resistant coolant hoses
Notes:
Can be used in contact with all foods except water in oil emulsions, high or low fat, and low moisture fats and oil.
Adhesives only.
